The first is the rate law in equivalent homogeneous media R hm =kA T 1-exp-[Formula presented], where rates depend on rate constants (k), total mineral surface area (A T), and the relative timescales of reactions (τ eq) and advection (τ a) Da=[Formula presented]. The liquid that is immiscible form heterogeneous mixtures. One could say that water, if it comes directly out of the tap, or has minerals added for bottled water, that it is a homogeneous mixture. It is always heterogenous because starch is only very slightly soluble in water and so more than a tiny amount forms a suspension. Describe how your parents an When oil and water are combined, they do not mix evenly, but instead form two separate layers.
